Edge states and topological phases in non-Hermitian systems
Kenta Esaki, Masatoshi Sato, Kazuki Hasebe +1
Topological stability of the edge states is investigated for non-Hermitian systems. We examine two classes of non-Hermitian Hamiltonians supporting real bulk eigenenergies in weak…
Zero modes, energy gap, and edge states of anisotropic honeycomb lattice in a magnetic field
Kenta Esaki, Masatoshi Sato, Mahito Kohmoto +1
We present systematic study of zero modes and gaps by introducing effects of anisotropy of hopping integrals for a tight-binding model on the honeycomb lattice in a magnetic field.…
Wave propagation through Cantor-set media: Chaos, scaling, and fractal structures
Kenta Esaki, Masatoshi Sato, Mahito Kohmoto
Propagation of waves through Cantor-set media is investigated by renormalization-group analysis. For specific values of wave numbers, transmission coefficients are shown to be gove…
Wave Propagation in the Cantor-Set Media: Chaos from Fractal
Kenta Esaki, Masatoshi Sato, Mahito Kohmoto
Propagation of waves in the Cantor-set media is investigated by a renormalization-group type method. We find fixed points for complete reflection, , and for complete transmi…
